Cuomo’s coronavirus TV briefings may have Biden, Sanders worried

Cuomo from all appearances is doing a good job.
This is in stark relief to Biden, who despite his national profile has been virtually unseen or heard from for over a week - most likely on purpose to strategize which form their sharpshooting would take.
In so doing Biden has conceded the initiative to the President and state Governors and deminished himself to a sideline heckler.

Cuomo is setting himself up to swoop in at the contested Dem Convention, and be the alternative to Joe and Bernie.

Cuomo is a chief executive encumbered by actually doing something to get his state through this. Much like the President he is in the field of battle on this. Sanders and Biden are on the sidelines. Sanders might have to vote on a bill, he is not responsible for anyone or anything really. Biden is not even in a job. They both are sitting essentially on the sidelines taking shots at those in the arena.

Cuomo is doing a good job for NY. He is working with the Feds, rallying his state and doing everything he can to reduce the impact of this virus. Even Newsome out in CA is stepping up. People responsible in a time of crisis have to do so or they will collapse.
